High-resolution anoscopy predictive modeling of anal canal cancer response after definitive chemoradiotherapy in COVID19 era.

PURPOSE: To develop a predictive index model, integrating both clinical and high-resolution anoscopy (HRA) features to further personalize the decision making process in anal canal carcinoma in COVID19 era. METHODS AND MATERIALS: We assess HRA parameters after definitive chemoradiotherapy in patients with anal canal malignant lesions. RESULTS: HRA features could be important to assess the effect of CRT and a risk stratification system should be introduced in clinical practice to better allocate therapeutic interventions. CONCLUSION: To our knowledge this is the first proposal for HRA findings in anal canal cancer after definitive CRT. We believe that a risk score can be useful to estimate the risk of treatment failure (in term of persistence disease and/or recurrence) and its clinical relevance should not to be underestimated.

Temporary intravascular shunts and limb salvage in civilian vascular trauma.

Background: Temporary intravascular shunts (TIVS) may allow quick revascularization and distal reperfusion, reducing the ischemic time (IT) when an arterial injury occurs. Furthermore, TIVS temporarily restore peripheral perfusion during the treatment of concomitant life-threatening injuries or when patients require evacuation to a higher level of care. Notwithstanding, there are still disputes regarding the use of TIVS, in view of the paucity of evidence in terms of potential benefits and with regard to the anticoagulation during the procedure. The present study aimed to assess TIVS impact, safety, and timing on limb salvage in complex civilian vascular traumas. Patients and methods: Data were retrieved from the prospective database of our department, which included all patients hospitalized with a vascular injury of the extremities between January 2006 and December 2022. Patients undergoing TIVS during vascular injury management were included in group A, and those who could not postpone immediate care for TIVS insertion were included in group B (control group). Data concerning the times required for extremity revascularization or other surgical procedures such as orthopedic interventions and the time of limb ischemia were compared between the two groups. A comparison of the postoperative course between the two groups was also performed. Results: A total of 53 patients were included: group A (TIVS insertion, n = 31) and group B (control, n = 22). Revascularization time significantly differed (p = 0.002) between the two groups, which is lower in group A (4.17 ± 2.37 h vs. 5.81 ± 1.26 h). TIVS positively affected the probability of limb salvage (p = 0.02). At multivariate analysis, the factors independently associated with limb salvage were TIVS usage, the necessity of hyperbaric oxygen therapy, and the total IT. In group A, there were three deaths and one major amputation, and in group B, there were two deaths and four major amputations. Conclusions: The use of TIVS minimizes revascularization time and improves limb salvage probability. A multidisciplinary approach is recommended, and correct surgical timing is key to ensure the best outcome.

HPV Vaccination after Primary Treatment of HPV-Related Disease across Different Organ Sites: A Multidisciplinary Comprehensive Review and Meta-Analysis.

OBJECTIVE: To assess evidence on the efficacy of adjuvant human papillomavirus (HPV) vaccination in patients treated for HPV-related disease across different susceptible organ sites. METHODS: A systematic review was conducted to identify studies addressing the efficacy of adjuvant HPV vaccination on reducing the risk of recurrence of HPV-related preinvasive diseases. Results were reported as mean differences or pooled odds ratios (OR) with 95% confidence intervals (95% CI). RESULTS: Sixteen studies were identified for the final analysis. Overall, 21,472 patients with cervical dysplasia were included: 4132 (19.2%) received the peri-operative HPV vaccine, while 17,340 (80.8%) underwent surgical treatment alone. The recurrences of CIN 1+ (OR 0.45, 95% CI 0.27 to 0.73; p = 0.001), CIN 2+ (OR 0.33, 95% CI 0.20 to 0.52; p < 0.0001), and CIN 3 (OR 0.28, 95% CI 0.13 to 0.59; p = 0.0009) were lower in the vaccinated than in unvaccinated group. Similarly, adjuvant vaccination reduced the risk of developing anal intraepithelial neoplasia (p = 0.005) and recurrent respiratory papillomatosis (p = 0.004). No differences in anogenital warts and vulvar intraepithelial neoplasia recurrence rate were observed comparing vaccinated and unvaccinated individuals. CONCLUSIONS: Adjuvant HPV vaccination is associated with a reduced risk of CIN recurrence, although there are limited data regarding its role in other HPV-related diseases. Further research is warranted to shed more light on the role of HPV vaccination as adjuvant therapy after primary treatment.

Acute emphysematous cholecystitis as a cause of pneumoperitoneum.

The authors report a rare case of acute emphysematous cholecystitis with pneumoperitoneum. Emphysematous cholecystitis is an uncommon variant of acute cholecystitis. Association with pneumoperitoneum is very rare and the finding of a macroscopic perforation of the gallbladder is possible only in a few cases. A review of the literature revealed 15 other cases of this combination. Diagnostic options and treatment modalities in these patients are discussed here.

Iatrogenic intramural hematoma of the duodenum caused by endoscopic therapy of bleeding peptic ulcer. A case report.

The authors report a case of intestinal obstruction resulting from a duodenal intramural hematoma after therapeutic upper digestive endoscopy with injection therapy. Intramural duodenal hematomas are rare clinical entities, mostly caused by blunt traumas. They may also, more rarely, be due to complications of peptic duodenal ulcers, or be the iatrogenic result of an endoscopic biopsy or placement of a percutaneous endoscopic gastrostomy catheter. It has recently become obvious that surgery is not necessary in most patients with duodenal hematomas. The treatment of choice for cases of intramural duodenal hematomas is of a conservative kind. Today we can employ minimally invasive diagnostic and therapeutic techniques for the percutaneous or laparoscopic evacuation of the hematoma, which seem to guarantee optimal results, compared to the high morbidity rate associated with laparatomy evacuation.

Perforated jejuneal diverticulosis. Case report and review of literature.

Acquired (non-Meckel's) jejunoileal diverticulosis is an uncommon disease, generally characterised by vague and unspecific symptoms. This rare condition is mainly expressed as acute complications: gastrointestinal haemorrhage, mechanic obstruction of the small intestine or perforated diverticulum, requiring urgent surgical intervention. The authors report a case of this unusual clinical occurrence characterized by a picture of abdominal pain due to perforation of jejuneal diverticulum. The final etiological diagnosis was possible only during surgery.
